Product details
Overview
ADR5041ARTZ-REEL from Analog Devices is a precision 2.5 V shunt voltage reference in a 3-lead SOT-23 (RT-3) package, designed for high-accuracy analog signal conditioning and data acquisition. It delivers ±0.1% initial accuracy, 75 ppm/°C max temperature coefficient, and operates from 50 µA to 15 mA over −40°C to +125°C - enabling use in automotive power supply monitoring and portable instrumentation.
For engineers reviewing the ADR5041ARTZ-REEL datasheet, ADR5041ARTZ-REEL pinout, ADR5041ARTZ-REEL application, or ADR5041ARTZ-REEL equivalent, key selection criteria include low operating current, no external capacitor requirement, stable performance with capacitive loads, and qualification for automotive-grade reliability under extended temperature conditions.
Technical Context
The ADR5041ARTZ-REEL implements a bandgap-based shunt reference architecture that cancels inherent transistor VBE temperature drift via curvature-compensated current summation. Its output remains stable without external compensation, even with load capacitance up to 1 µF.
It functions as a two-terminal device requiring only an external bias resistor to set operating current; dynamic output impedance is 0.2 Ω across 50 µA–15 mA, and turn-on settling time is 35 µs into zero load capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500 V nominal at 100 µA - matches standard ADC reference rails and enables direct interface with 12-bit+ SAR converters. |
| Initial Accuracy | ±0.1% (±2.5 mV) - ensures ≤1 LSB error in 12-bit systems without calibration. |
| Temp. Coefficient | ≤75 ppm/°C over −40°C to +125°C - contributes <±0.225% full-scale drift across automotive temperature range. |
| Operating Current | 50 µA to 15 mA - supports ultra-low-power sensor nodes and high-current precision DAC buffers. |
| Voltage Noise | 3.2 µV rms (0.1–10 Hz), 150 µV rms (10 Hz–10 kHz) - suitable for 16-bit data acquisition without additional filtering. |
| Settling Time | 35 µs (CLOAD = 0) - enables fast power-up in battery-powered measurement cycles. |
| Dynamic Impedance | 0.2 Ω - minimizes output voltage shift under dynamic load transients in closed-loop systems. |
Pinout & Package
ADR5041ARTZ-REEL uses a 3-lead SOT-23 (RT-3) package per JEDEC TO-236-AB, with 1.30 mm × 2.10 mm footprint and 1.10 mm height. Pin 3 (T) must be connected to V+ per datasheet recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (V+) | Anode / Reference Output | Provides stable 2.5 V output; connects to load and bias resistor; requires external current sourcing. |
| 2 (V−) | Cathode / Ground Reference | Serves as return path for shunt current; ties to system ground or negative rail in floating configurations. |
| 3 (T) | Temperature Sense / V+ Tie | Internally connected to V+; datasheet recommends external connection to V+ to improve thermal stability and reduce hysteresis. |
Key Features
| Feature | Design Value |
|---|---|
| No external capacitor required | Stable with any capacitive load up to 1 µF - eliminates BOM cost and layout area for decoupling caps in space-constrained designs. |
| PIN-compatible with LM4040/LM4050 | Direct drop-in replacement in existing SOT-23-3 layouts - enables upgrade to higher accuracy and lower drift without PCB revision. |
| Automotive qualified variant available | ADR5041WARTZ-R7 meets AEC-Q100 requirements - supports functional safety-critical voltage monitoring in ADAS and body control modules. |
| Wide operating current range | 50 µA minimum enables operation from coin-cell batteries; 15 mA maximum supports driving multiple op-amp inputs simultaneously. |
| Low voltage noise | 3.2 µV rms (0.1–10 Hz) - preserves SNR in high-resolution weigh scale and medical sensor front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM4040C25IDBZR | ±0.5% initial accuracy, 100 ppm/°C max TC, 60 µA min operating current | Lacks automotive qualification; higher drift limits use in high-temp industrial sensors | Select when cost sensitivity outweighs precision needs and ambient temperature stays below 85°C. |
| ADR3425ARJZ-R7 | 2.5 V series reference, 300 µA quiescent current, SOIC-8 package, ±0.1% accuracy | Requires external bypass cap; not pin-compatible; higher supply current precludes ultra-low-power use | Choose for systems needing low-output-impedance buffered reference with better PSRR than shunt topology. |
Compared with LM4040C25IDBZR, ADR5041ARTZ-REEL offers 5× tighter initial accuracy and 30% lower tempco - critical for uncalibrated field instruments. Versus ADR3425ARJZ-R7, it reduces standby current by >99% and fits in 40% less board area, but requires external bias design.

FAQ
What is the output voltage tolerance of ADR5041ARTZ-REEL at 25°C?
The ADR5041ARTZ-REEL has a nominal output voltage of 2.500 V with ±0.1% initial accuracy at 100 µA, corresponding to a guaranteed range of 2.4975 V to 2.5025 V at 25°C. This specification is verified per Table 3 in the Rev. E datasheet and applies to Grade B devices in the ADR5041 series, which includes ADR5041ARTZ-REEL.
Does ADR5041ARTZ-REEL require an external capacitor for stability?
No, ADR5041ARTZ-REEL does not require an external capacitor for stability. Its internal design ensures stability with any capacitive load up to 1 µF, as confirmed in the Applications Information section and Figure 14/17 of the datasheet. This eliminates the need for external compensation components in most implementations.
What is the minimum operating current for ADR5041ARTZ-REEL over temperature?
The minimum operating current for ADR5041ARTZ-REEL is 60 µA across the full −40°C to +125°C temperature range, per Table 3's "MINIMUM OPERATING CURRENT" row. At 25°C, it is specified at 50 µA, but derates to 60 µA to guarantee regulation under worst-case thermal conditions.
Is ADR5041ARTZ-REEL qualified for automotive applications?
ADR5041ARTZ-REEL itself is the commercial-grade version. For automotive use, Analog Devices offers the ADR5041WARTZ-R7 variant, which is AEC-Q100 qualified and manufactured under controlled automotive processes. The ADR5041ARTZ-REEL is not rated for automotive qualification, though it operates across the same −40°C to +125°C temperature range.
How is the ADR5041ARTZ-REEL pinout configured in SOT-23?
ADR5041ARTZ-REEL uses a standard 3-lead SOT-23 (RT-3) package: Pin 1 is V+ (anode/output), Pin 2 is V− (cathode/ground), and Pin 3 is T (temperature sense terminal). Per Figure 1 and Note 1 in the datasheet, Pin 3 must be externally connected to V+ to minimize hysteresis and optimize thermal performance.
